Description

Technical Field

[0001] This utility model relates to the field of textile technology, and in particular to a yarn guide nozzle. Background Technology

[0002] In the textile industry, the yarn guide nozzle, as a core yarn guiding component of a circular knitting machine, directly affects the stability of yarn feeding, weaving efficiency, and the final fabric quality. It is widely used in various fabric production scenarios, including knitting and weaving. However, with the development of textile technology towards higher speeds and greater precision, existing yarn guide nozzles have gradually revealed several shortcomings in practical applications, making it difficult to meet the demands of modern weaving production. Specific problems include: Insufficient installation and adjustment flexibility: Traditional yarn guide nozzles are mostly designed with fixed holes, allowing connection to the circular knitting machine via bolts in a single location. When the installation height and horizontal position of the yarn guide nozzle need to be adjusted according to the yarn type (such as cotton yarn, chemical fiber yarn, elastic yarn) or fabric weaving density, it is necessary to disassemble and re-drill holes or replace the adapter bracket. This operation is cumbersome and has low adjustment accuracy, which not only prolongs the equipment debugging time but also easily causes wear on the mounting base due to repeated disassembly, affecting the positioning stability of the yarn guide nozzle.

[0003] Poor yarn feeding smoothness: Some yarn guide nozzles have right-angle turns or sharp edges, which makes it easy for the yarn to rub against the inner wall of the yarn guide head during high-speed feeding, resulting in yarn fuzzing and breakage. This is especially true for fine denier or elastic yarns, where the damage caused by friction is more obvious, directly reducing the appearance quality of the fabric (such as the appearance of fuzz and holes). At the same time, some yarn guide nozzles have no optimized yarn guide channel design, which makes the yarn prone to deviation and tangling during feeding, requiring frequent manual intervention and seriously restricting the continuous operation efficiency of the circular knitting machine.

[0004] Low adaptability of yarn guide auxiliary structures: In modern knitting production, to further improve the stability of yarn feeding, it is often necessary to match the yarn guide nozzle with a yarn guide wheel assembly (to reduce yarn tension fluctuations). However, most existing yarn guide nozzles do not have a dedicated installation structure for the yarn guide wheel assembly. Users need to drill holes or weld the installation parts onto the yarn guide nozzle body themselves. This not only damages the structural strength of the yarn guide nozzle, but also easily leads to misalignment between the yarn guide wheel assembly and the yarn guide channel due to installation position deviation, which in turn increases the resistance to yarn feeding and fails to give full play to the auxiliary role of the yarn guide wheel assembly.

[0005] Airflow interference affects yarn positioning: During high-speed knitting, a complex airflow field forms inside the circular knitting machine, especially in the area near the knitting needle bed at the lower end of the yarn guide nozzle, where airflow disturbances are more pronounced. Traditional yarn guide nozzles often have curved or irregularly shaped bottoms, which cannot effectively guide airflow. Turbulent airflow can cause the yarn to drift before entering the knitting area, resulting in inaccurate yarn feeding position, leading to uneven fabric density, missed needles, and other quality problems, increasing the defect rate.

[0006] Poor stability in the installation and positioning of the yarn guide ring: The yarn guide ring is a key component in the yarn guide nozzle that directly contacts and guides the yarn, and its installation accuracy directly affects the yarn direction. Existing yarn guide nozzles often employ a simple perforation design for the yarn guide ring installation, lacking a positioning and limiting structure. Under long-term high-speed vibration conditions, the yarn guide ring is prone to displacement or loosening, leading to changes in the yarn transport path. This not only affects fabric quality but may also cause equipment jamming due to the yarn guide ring falling off, increasing maintenance costs.

[0007] In view of the above-mentioned shortcomings, the designer actively researched and innovated in order to create a yarn guide that has greater industrial value. Summary of the Invention

[0008] To solve the above-mentioned technical problems, the purpose of this utility model is to provide a yarn guide nozzle.

[0009] The present invention provides a yarn guide nozzle, comprising a mounting body, a through-strip mounting groove in the middle of the mounting body, a fastening bolt passing through the mounting groove to fix the mounting body on a circular knitting machine, a bent yarn guide head at the bottom of the mounting body, and an inclined yarn guide ring at the end of the yarn guide head.

[0010] This yarn guide includes a mounting body for connection with a circular knitting machine. The mounting body has a long, through-slot in the middle. During actual assembly, simply pass the fastening bolt through the mounting slot to flexibly adjust the fixed position of the mounting body on the circular knitting machine and complete the secure installation. This effectively solves the problems of fixed installation position and inconvenient adjustment of traditional yarn guides. The bottom of the mounting body has an integrally formed yarn guide head with a bent structure, which can adapt to the turning requirements of the yarn conveying path inside the circular knitting machine. The end of the yarn guide head is equipped with an inclined yarn guide ring, which allows the yarn to pass smoothly through the yarn guide ring and be stably conveyed along the inclined direction. This reduces friction loss between the yarn and the yarn guide components and ensures that the yarn maintains a precise direction during high-speed conveying, improving the continuity of weaving operations and the quality of fabric formation.

[0011] Furthermore, mounting screw holes are provided at a position slightly below the center of the mounting body surface, and these mounting screw holes are used to install the yarn guide wheel assembly.

[0012] On the surface of the yarn guide nozzle, near the center and slightly lower, there is a specially designed mounting screw hole. The core function of this screw hole is to provide a stable assembly interface for the yarn guide wheel assembly. After the yarn guide wheel assembly is installed in place through this screw hole, it can form a precise fit with the yarn guide channel of the yarn guide nozzle. During the yarn conveying process, the rolling of the yarn guide wheel reduces the friction between the yarn and the components, while also helping to stabilize the yarn tension, prevent the yarn from shifting or tangling, and further improve the smoothness and stability of the overall yarn guiding process, adapting to the conveying needs of different types of yarn.

[0013] Furthermore, the end of the yarn guide head has a mounting hole for installing a yarn guide ring.

[0014] The end of the yarn guide head is specially equipped with a mounting hole for precise assembly of the yarn guide ring. This provides a stable mounting base for the yarn guide ring, preventing it from shifting or loosening during high-speed yarn transport. It ensures that the yarn guide ring is always on the preset yarn guide path, allowing the yarn to pass smoothly through the yarn guide ring and maintain a stable direction. This reduces frictional wear between the yarn and the yarn guide components, ensuring the continuity of the weaving operation and the quality of the fabric formation.

[0015] Furthermore, the inner side of the yarn guide head has an arc-shaped opening, and the opening has a trumpet-shaped structure that is narrow on the outside and wide on the inside.

[0016] The inner side of the yarn guide head is designed with an arc-shaped opening, and this opening has an overall trumpet-shaped structure that is narrow on the outside and wide on the inside. This design not only avoids scratching damage to the yarn caused by sharp edges, but also acts as a "guide channel" to allow the yarn to easily enter from the narrower outer side of the opening and then smoothly transition along the gradually widening inner side. This effectively reduces the resistance and jamming of the yarn during the conveying process, and can also adapt to yarns of different thicknesses, ensuring that the yarn always moves stably along the preset path, providing a guarantee for subsequent precise yarn guiding.

[0017] Furthermore, the bottom of the yarn guide head is flat, which makes the airflow at the lower end of the yarn guide head stable.

[0018] The bottom of the yarn guide head adopts a flat design. This flat structure can stabilize and comb the airflow generated during the operation of the circular knitting machine, preventing the airflow from forming turbulent vortices at the lower end of the yarn guide head. This prevents airflow disturbance from affecting yarn delivery, allowing the yarn to maintain a stable direction in the critical links near the weaving area. It reduces yarn deviation and drifting caused by airflow interference, ensures accurate connection of subsequent weaving actions, and improves the consistency and quality stability of fabric formation.

[0019] Furthermore, the yarn guide head and the mounting body are stepped, with the side end face of the yarn guide head higher than the side end face of the mounting body.

[0020] The connection between the yarn guide head and the mounting body adopts a stepped design, and the side end face of the yarn guide head is slightly higher than the side end face of the mounting body. This structure not only makes the connection boundary between the two clearer, avoiding mutual interference between the mounting body and the yarn guide head during assembly or use, but also leaves more reasonable space around the yarn guide head, which facilitates the smooth conveying of yarn in the yarn guide head area. At the same time, it reduces the impact of yarn lint, dust and other impurities that may adhere to the surface of the mounting body on the yarn guiding process, ensuring stable and reliable yarn guiding action, and further adapting to the complex component layout requirements inside the circular knitting machine.

[0021] Furthermore, there is an inclined guide plate on the inner side of the lower end of the yarn guide head.

[0022] An inclined guide plate is provided on the inner side of the lower end of the yarn guide head. This guide plate is mainly used to guide and comb the airflow generated during the operation of the circular knitting machine. Through the reasonable design of the inclination angle, the airflow direction near the yarn guide head can be effectively regulated, avoiding the impact or disturbance of turbulent airflow on the yarn. This ensures that the yarn remains stable during the conveying process, reduces yarn drifting and deviation caused by airflow interference, and ensures that the yarn can accurately enter the subsequent weaving stage, providing a stable guarantee for improving the quality of fabric formation.

[0023] Furthermore, the top of the yarn guide ring extends beyond the end face of one side of the yarn guide head.

[0024] The top of the yarn guide ring is designed to extend beyond the side of the yarn guide head. This structure allows the yarn guide ring to contact and guide the yarn more forward, avoiding unnecessary friction between the yarn and the edge of the yarn guide head before entering the yarn guide ring. At the same time, the extended part provides a wider entry angle for the yarn. Even if there is a slight deviation during the yarn feeding process, it can be successfully captured and corrected by the yarn guide ring, reducing yarn jamming or deviation, ensuring that the yarn always passes through the preset path stably, and improving the fault tolerance and smoothness of the yarn guiding process.

[0025] By means of the above-described solution, the present invention has at least the following advantages: Improved installation and adjustment flexibility, reduced debugging costs and difficulty: By setting a through-type long strip mounting groove in the middle of the mounting body, replacing the traditional fixing hole structure, the mounting body can be fixed by fastening bolts passing through the mounting groove. There is no need to disassemble, drill holes or replace brackets. The height and horizontal position of the yarn guide nozzle on the circular knitting machine can be flexibly adjusted to adapt to the needs of different yarn types (such as cotton yarn, chemical fiber yarn, elastic yarn) and fabric weaving density. This not only shortens the equipment debugging time, but also avoids wear of the mounting seat caused by repeated disassembly, ensures the positioning stability of the yarn guide nozzle, and reduces equipment maintenance costs.

[0026] Optimize the yarn transport path to reduce damage and improve transport smoothness: The yarn guide head with a bent structure at the bottom of the main body can adapt to the yarn turning requirements inside the circular knitting machine; the inner arc shape of the yarn guide head and the flared opening that is narrower on the outside and wider on the inside prevent sharp edges from scratching the yarn, while providing a smooth transition channel for the yarn, reducing transport resistance and jamming, and adapting to yarns of different thicknesses; the yarn guide ring is set at an angle and its top extends beyond one end face of the yarn guide head, which reduces friction between the yarn and the edge of the yarn guide head, and expands the yarn entry angle, reducing the risk of jamming caused by slight deviation, effectively reducing yarn fuzzing and breakage, ensuring the continuity of weaving operations, and improving the appearance quality of the fabric (such as reducing fuzz and holes).

[0027] Enhanced adaptability of the yarn guide auxiliary structure and improved yarn feeding stability: The pre-set mounting screw holes on the lower center of the mounting body provide a dedicated and stable assembly interface for the yarn guide wheel assembly, eliminating the need for additional drilling or welding, thus avoiding damage to the strength of the yarn guide nozzle structure, while ensuring precise fit between the yarn guide wheel assembly and the yarn guide channel; after installation, the yarn guide wheel assembly can reduce friction between the yarn and the components through rolling, stabilizing yarn tension, preventing yarn deviation and tangling, further improving the stability of the yarn guiding process, and adapting to the needs of modern knitting production for auxiliary structures.

[0028] Optimized airflow guidance ensures accurate yarn positioning: The flat bottom design of the yarn guide head can organize the airflow generated by the circular knitting machine, preventing the formation of turbulent vortices at the lower end of the yarn guide head; the inclined guide plate on the inner side of the lower end of the yarn guide head can further regulate the airflow direction, prevent turbulent airflow from impacting and disturbing the yarn, effectively reduce the drifting and deviation of the yarn near the knitting needle bed area, ensure accurate yarn feeding position, reduce the incidence of quality problems such as uneven fabric density and missed needles, reduce the defect rate, and improve the consistency of fabric formation.

[0029] Enhanced yarn guide ring positioning stability and reduced equipment failure risk: The specially designed yarn guide ring mounting hole at the end of the yarn guide head provides a stable mounting base for the yarn guide ring, avoiding yarn guide ring offset and loosening caused by long-term high-speed operation vibration, ensuring that the yarn guide ring is always in the preset yarn guiding path, which not only ensures the stability of the yarn conveying path, but also prevents equipment jamming caused by the yarn guide ring falling off, reduces maintenance costs and downtime, and improves equipment operation reliability.

[0030] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this invention are described in detail below with reference to the accompanying drawings.

It should be understood that the following drawings only show a certain embodiment of this utility model and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

Mounting body; 2. Mounting groove; 3. Yarn guide head; 4. Yarn guide ring; 5. Mounting screw hole; 6. Guide plate. Detailed Implementation

[0033] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0034] See Figure 1 When assembling with a circular knitting machine, the fastening bolts are first passed through the long, narrow mounting groove 2 in the middle of the mounting body 1. The long, narrow structure of the mounting groove 2 allows for flexible adjustment of the mounting body 1's fixed position on the circular knitting machine. After determining the appropriate position, the bolts are tightened to securely fix the mounting body 1. During operation, the yarn first enters the bent yarn guide head 3 at the bottom of the mounting body 1. The bent structure of the yarn guide head 3 adapts to the turning requirements of the yarn conveying path inside the circular knitting machine. Then, through the inclined yarn guide ring 4 at the end of the yarn guide head 3, the yarn is precisely guided to the weaving area along the inclined direction of the yarn guide ring 4, completing stable yarn guidance. The mounting groove 2 replaces the traditional fixing hole, allowing for flexible adjustment of the installation position without disassembly or drilling, adapting to different yarn types and weaving density requirements, shortening debugging time and avoiding wear on the mounting base. The bent yarn guide head 3 can smoothly accept yarn turning, and the inclined yarn guide ring 4 can reduce friction between the yarn and the yarn guide components, reducing the probability of yarn fuzzing and breakage, while ensuring the accurate direction of the yarn during high-speed conveying, improving the continuity of weaving operations and the quality of fabric formation.

[0035] Using the pre-set mounting screw holes 5 located slightly below the center of the mounting body 1, the yarn guide wheel assembly is precisely assembled onto the mounting body 1, ensuring a proper fit between the yarn guide wheel assembly and the yarn guide channel of the yarn guide nozzle. When the yarn enters the conveying path of the yarn guide nozzle, it first passes through the yarn guide wheel assembly fixed by the mounting screw holes 5. The rolling action of the yarn guide wheel assembly guides the yarn forward before continuing to be conveyed to the subsequent yarn guiding structure. The mounting screw holes 5 provide a dedicated and stable mounting base for the yarn guide wheel assembly, eliminating the need for additional drilling or welding on the mounting body 1, thus avoiding damage to the structural strength of the mounting body 1. At the same time, it ensures the precise installation position of the yarn guide wheel assembly, effectively reducing sliding friction between the yarn and components during yarn conveying, reducing yarn tension fluctuations, preventing yarn deviation, tangling, or damage, and ensuring that the yarn is always conveyed along a stable path. This further improves the smoothness and reliability of the yarn guiding process, adapting to the high-speed conveying needs of different types of yarn.

[0036] The yarn guide ring 4 is precisely and securely mounted on the yarn guide head 3 through the mounting hole at the end of the yarn guide head 3, ensuring that the yarn guide ring 4 is always on the preset yarn guide path during the subsequent yarn feeding process. When the yarn enters the area of ​​the yarn guide head 3, it will enter the yarn guide ring 4 positioned by the mounting hole along the structural direction of the yarn guide head 3, and be stably fed to the weaving area under the constraint and guidance of the yarn guide ring 4. The mounting hole at the end of the yarn guide head 3 provides a dedicated mounting and positioning structure for the yarn guide ring 4, avoiding the problem of the yarn guide ring 4 being prone to displacement and loosening due to vibration under the traditional simple perforation design. It can always maintain the relative position stability of the yarn guide ring 4 and the yarn guide head 3, thereby ensuring the accuracy of the yarn feeding path, reducing abnormal friction between the yarn and the yarn guide head 3 and the yarn guide ring 4, reducing the probability of yarn fuzzing and breakage, ensuring the continuity of the weaving operation, and also avoiding the risk of equipment jamming caused by the displacement of the yarn guide ring 4, improving the reliability of the yarn guiding process and the quality of fabric formation.

[0037] Meanwhile, the yarn guide ring 4 and the yarn guide head 3 are assembled with an interference fit, so the yarn guide ring 4 can be quickly disassembled and assembled when necessary, which facilitates daily maintenance and repair.

[0038] See Figure 2 Through the mounting hole at the end of the yarn guide head 3, the yarn guide ring 4 is precisely and securely mounted on the yarn guide head 3, ensuring that the yarn guide ring 4 is always on the preset yarn guide path during the subsequent yarn feeding process. When the yarn enters the area of ​​the yarn guide head 3, it will enter the yarn guide ring 4 positioned by the mounting hole along the structural direction of the yarn guide head 3, and be stably fed to the weaving area under the constraint and guidance of the yarn guide ring 4. The mounting hole at the end of the yarn guide head 3 provides a dedicated mounting and positioning structure for the yarn guide ring 4, avoiding the problem of the yarn guide ring 4 being prone to displacement and loosening due to vibration under the traditional simple perforation design. It can always maintain the relative position stability of the yarn guide ring 4 and the yarn guide head 3, thereby ensuring the accuracy of the yarn feeding path, reducing abnormal friction between the yarn and the yarn guide head 3 and the yarn guide ring 4, reducing the probability of yarn fuzzing and breakage, ensuring the continuity of the weaving operation, and also avoiding the risk of equipment jamming caused by the displacement of the yarn guide ring 4, improving the reliability of the yarn guiding process and the quality of fabric formation.

[0039] As the circular knitting machine operates at high speed, complex airflow is generated inside. When the airflow passes through the yarn guide head 3 area, the flat structure at the bottom of the yarn guide head 3 helps to comb and guide the airflow, preventing the formation of turbulent vortices or disordered flow at the lower end of the yarn guide head 3, thus keeping the airflow at the lower end of the yarn guide head 3 stable. During this process, the stable airflow will not impact or disturb the yarn being fed to the weaving area through the yarn guide head 3, ensuring that the yarn can move stably along the preset path. The flat design at the bottom of the yarn guide head 3 eliminates the need for additional airflow adjustment components, achieving airflow stability through its own structure. This simplifies the overall structure of the yarn guide head and effectively prevents yarn drifting and deviation caused by airflow turbulence, ensuring the accuracy of the yarn position when fed into the weaving area, reducing quality defects such as uneven fabric density and missed needles, and avoiding jamming caused by yarn deviation, ensuring the continuity of weaving operations, and improving fabric forming quality and production efficiency.

[0040] The mounting body 1 serves as the basic component connecting to the circular knitting machine. Its stepped structure with the yarn guide head 3, and the design where the side face of the yarn guide head 3 is higher than the side face of the mounting body 1, create a clear spatial boundary in the connection area. When the yarn enters the yarn guide head 3 from below the mounting body 1 and is conveyed to the weaving area, the higher side face of the yarn guide head 3 prevents yarn lint, dust, and other impurities that may be attached to the surface of the mounting body 1 from directly contacting the yarn. Simultaneously, the stepped structure provides an independent and smooth space for the yarn to be conveyed within the yarn guide head 3, preventing mutual interference between the mounting body 1 and the yarn guide head 3 on the yarn conveying path. No additional protective or isolation components are needed; the stepped structure between the mounting body 1 and the yarn guide head 3 alone ensures the cleanliness and spatial independence of the yarn conveying environment, reducing contamination or scratching of the yarn by impurities. It also prevents yarn deviation and jamming caused by interference between components, ensuring that the yarn is always stably conveyed along the preset path of the yarn guide head 3, improving the reliability of the yarn guiding process, adapting to the complex internal component layout of the circular knitting machine, and further guaranteeing the quality of fabric formation.

[0041] As the circular knitting machine operates at high speed, it generates complex airflow. When the airflow reaches the lower part of the yarn guide head 3, the inclined guide plate 6 installed on the inner side of the lower part of the yarn guide head 3 guides and regulates the airflow according to its own inclination angle. This allows the airflow, which might otherwise be turbulent, to flow orderly along the inclination direction of the guide plate 6, preventing the airflow from forming disordered vortices or reverse impacts at the lower part of the yarn guide head 3. The yarn being conveyed to the knitting area through the yarn guide head 3 will maintain a stable direction in the stable airflow environment created by the guide plate 6, unaffected by turbulent airflow. The inclined guide plate 6 can directly optimize the airflow through its own structure, eliminating the need for additional airflow adjustment devices. This simplifies the overall structure of the yarn guide head and effectively prevents yarn drifting and deviation caused by airflow impact. It ensures that the yarn is accurately positioned in the key conveying link near the knitting needle bed, reducing quality problems such as uneven fabric density and missed needles caused by yarn position deviation. This improves the continuity of knitting operations and the quality of fabric formation, while also reducing yarn loss caused by airflow interference.

[0042] After the yarn is conveyed from upstream to the yarn guide head 3 area, it will first come into contact with the yarn guide ring 4 at the end of the yarn guide head 3. Since the top of the yarn guide ring 4 extends beyond the end face of the yarn guide head 3, the yarn guide ring 4 can contact the yarn more forward than the end face of the yarn guide head 3, thus guiding and constraining the yarn in advance. This allows the yarn to be initially positioned before entering the interior of the yarn guide ring 4. Subsequently, the yarn is stably conveyed to the weaving area along the channel of the yarn guide ring 4. The design of the top of the yarn guide ring 4 extending beyond the end face of the yarn guide head 3 can avoid friction between the yarn and the edge of the end face of the yarn guide head 3 during the process of approaching the yarn guide ring 4, reducing the risk of yarn fuzzing and wear. At the same time, the forward contact position can provide a wider entry angle for the yarn. Even if there is a slight deviation during the yarn conveying, it can be successfully captured by the yarn guide ring 4 and guided back to the correct path, reducing the probability of yarn jamming or deviation, ensuring that the yarn is always stably conveyed along the preset direction, improving the fault tolerance and smoothness of the yarn guiding process, and thus ensuring the continuity of the weaving operation and the quality of fabric formation.
